This paper studies how to address the security challenges caused by untrusted and nontransparent energymarkets in Peer-to-Peer(P2P) energy trading.
The contributions include:
The rationale of the proposed approach is depicted as follows.
The energy blockchain performs the consensus process on pre-selected EAGs with moderate cost. These EAGs collect and managetheir local transaction records. The transaction records arestructured into blocks after finishing the consensus process among the EAGs, and thus stored in the memory pool.
A credit bank in each authorized EAG works as atrusted bank node with enough energy coins. The credit banks provide energy coin loans for energy nodes according to their credit values, then the energy coins will be transferred from the credit banks’ accounts to the wallet addresses shared between the credit banks and borrowers.
Present the problem definition about theamount of energy-coin loan and loan pricing (i.e., interest rateand penalty rate) for borrowers to maximize economic benefitsof credit banks. Energy buyers without enough energy coinsact as borrowers to apply for loans from the credit bank in alocal EAG. After that, the borrowers worked as energy buyerscan buy energy from energy sellers.
Security analysis shows that this energy blockchain achieves secure energy trading, and numerical results illustrate that the energy blockchain and the credit-based payment scheme are effective and efficient for energy trading.
